Surveying Details

-----------------------------

9 November 1970. A request to purchase the submarine was made by C J Oldfield.

18 December 1985. The site was examined on 3 July 1985 at 60 03 13N, 000 57 57W or decca [n scot] red a 8.15, green f 34.65, purple d 64.50. The least echosounder depth was 97 in a general depth of 103 metres. No scouring was observed. The side scan sonar indicated a height of 5.6 metres, length of 50 metres (164 feet) and beam of 10 metres (32 feet). The vessel is lying with its keel on an orientation of 015/195 degrees. The sonar trace indicates apparently a submarine.

Report by Naval Party

Note: this could also possibly be the wreck of the British submarine C34 - see 59 51 00N, 001 05 00W.

The identity cited by the Hydrographic Office for this loss is evidently incorrect. Le Fleming identifies what is evidently this boat as UC55 (rather than U55) and records her sinking 'off Lerwick' in 1917.

This boat was a unit of the 64-strong UCII class of coastal minelaying submarine, and was built at Danzig Dockyard in 1916. Significant variations apparently existed within the class but are not individually cited in the available literature.
